Speaking to media persons, Mr. Jagdish Vadalia Senior Manager for Product Development of the company said, " GL's Message Automation & Protocol Simulation(TM) (MAPS(TM)) is an advanced protocol simulator/tester traffic generator for SIP-ISUP simulation over IP. MAPS(TM) SIP I can simulate SIP-ISUP signaling specification as defined by the ITU / IETF standards ITU-T Q.1912.5. MAPS(TM) product with SIP-I provides only the IP side of the Gateway at both ingress and/or egress depending on what one is trying to emulate. In general, MAPS(TM) is a powerful Protocol Test platform, supporting a wide range of protocols including TDM, IP, and Wireless infrastructure protocols."
He added, "MAPS(TM) SIP I is designed for SIP-I Testing and it can simulate Signaling Gateway / Softswitch as a User Agents Client (UAC), which sends SIP requests with ISUP message and User Agent Server (UAS), receiving and returning SIP responses with proper ISUP message attached."
Mr.Vadaia further added, "The MAPS(TM) SIP I supports powerful tools like Message Editor, Script Editor and Profile Editor which allow new scenarios to be created or existing scenarios to be modified using SIP-I messages and parameters. It gives the flexibility of modifying any message so that we can easily duplicate the messages generated by any entity to resolve interoperability issues."
